Clive Cussler - Skeleton Coast

“That these stones make better gravel than gems.” Max said, making his voice shrill and adding an atrocious Dutch accent. Abala almost leapt to his feet at the insult, but Max waved him down. “But on preliminary review I judge them satisfactory for our transaction.”

He pulled a flat piece of topaz from his pants pocket, its surfaces deeply scratched. “As you know,” he said in a lecturing tone, “diamond is the hardest substance on earth. Ten on the Mohs’ scale, to be exact.

Quartz, which is number seven, is often used to fool the uninitiated into thinking they are getting the deal of a lifetime.”

From the same pocket he plucked an octagonal shaft of crystal. Bearing down with considerable force he raked the quartz across the flat chunk of topaz. The edge slid off without making a mark. “As you can see, topaz is harder than quartz and hence can’t be scratched. It is eight on the Mohs’ scale, in fact.” He then took one of the smaller diamonds and ran it across the topaz. With a spine-shivering squeal the edge of the gem dug a deep scratch into the blue semiprecious stone. “So what we have here is a stone harder than eight on the Mohs’ scale.”

“Diamond,” Abala said smugly.

Max sighed as if a recalcitrant student had made a gaff. He was enjoying playing at gemologist. “Or corundum, which is nine on the Mohs’ scale. The only way to be certain this is a diamond is to test its specific gravity.”

Although Abala had dealt with diamonds many times before he knew little of their properties other than their value. Without realizing it, Hanley had piqued his interest and lowered his guard. “What is specific gravity?” he asked.

“The ratio of a stone’s weight verses the volume of water it displaces. For diamond it is exactly three point five two.” Max fiddled with his scale for a moment, calibrating it with a set of brass weights carried in a velvet-lined case. Once the scale had been zeroed he set the largest stone on the pan. “Point two two five grams. Eleven and a half carats.” He opened one of the plastic graduated cylinders and dropped the stone inside, noting how much water the gem displaced in his notebook. He then tapped the numbers into the calculator. When he saw the resulting number he glared at Raif Abala.

Abala’s eyes went wide with indignant anger. His troopers tightened their cordon. A gun was pressed against Juan’s back.

Unperturbed by the sudden show of aggression, Max let his expression go neutral and then allowed a smile to creep across his face. “Three point five two. This, gentlemen, is a real diamond.”

Colonel Abala slowly lowered himself into his seat and fingers that had been ounces away from squeezing triggers were relaxed. Juan could have killed Hanley for playing his role a little too well.

Max tested eight more random stones and each time the results were the same.

“I have held up my end of the bargain,” Abala said. “A quarter pound of diamonds for the weapons.”

While Hanley tested more stones, Linc led Abala to the open container, signaling to a crewman on the freighter to lower it to the quay. The wooden piers holding up the jetty creaked under the weight. Five rebel soldiers went with them. By the glare of a flashlight, Abala and his men grabbed ten AK-47s from different racks and about a hundred rounds of ammunition, using a machete to cut open the wax-coated paper blocks of bullets.

Making sure he stood close by Abala in case the troops tried something, Linc watched as the men laboriously loaded the shiny brass cartridges into the AK’s distinctive banana magazines. Juan, who was wearing a lightweight flak jacket under his bulky sweatshirt, stuck to Max for the very same reason. Each assault rifle was fired ten times, two three-round bursts and four single shots aimed carefully at a target stapled to the side of the disused warehouse. The gunfire echoed across the broad reach of the river and sent dozens of birds winging into the night. A soldier ran to the warehouse to inspect the damage, shouting an encouragement. Abala grunted at Linc, “Good. Very good.”

Back at the table Hanley carried on his inspection, setting the empty sack on the scale and noting its weight in his notebook. Then, under the watchful eye of one of Abala’s officers, he used a long-handled spoon to coax the rough stones back into the bag. Once he had them all, he weighed the bag again. On the calculator he subtracted the bag’s weight from the total. He looked over his shoulder at Cabrillo and whispered, “We are eight carats short.”

Depending on the stones, those eight carats could translate into tens of thousands of dollars. Juan shrugged. “I’ll just be happy to get out of here alive. Let it go.” Cabrillo called over to Linc, who was going over one of the RPGs with Abala and a rebel who had the professional look of a sergeant,

“Captain Lincoln, the port authorities won’t hold our berth in Boma. We should get going.”

Linc turned to him. “Of course, Mr. Cabrillo. Thank you.” He looked back to Abala. “I wish I had more weapons to offer you, Colonel, but coming across this shipment was a surprise to me and my crew.”

“If you, ah, ever get such a surprise again, you know how to contact us.”

They had reached the table. Linc asked Max, “Everything all set?”

“Yes, Captain, everything’s in order.”

Abala’s smile took on an even oilier sheen. He’d intentionally shorted them on the deal, knowing that his overwhelming number of armed men would intimidate them into accepting fewer stones than agreed. The missing diamonds were in his uniform blouse pocket and would go a long way in fattening his Swiss bank account.

“Let’s go then, gentlemen.” Linc took the bag of diamonds from Max and strode toward the gangplank, Cabrillo and Hanley hurrying to match his long strides. The moment before they reached the gangway Abala’s men swung into action. The two closest to the ramp stepped forward to block it while dozens of rebels rushed out of the jungle firing into the air and screaming like banshees. At least a dozen men swarmed the container, trying to unhook the cargo derrick.

The effect would have been overwhelming had the Corporation team not expected a double-cross.

A second before Abala shouted his order to attack, Cabrillo and Linc had started running. They were on the two rebels at the base of the gangplank before either had time to bring their weapons to bear. Linc bodily tossed one young soldier into the space between the freighter and the quay as Juan jammed his fingers into the other’s throat just hard enough to make him retch. As the rebel coughed, Juan ripped the AK-47 out of his hands and sank the butt into the soldier’s stomach. He fell into a fetal ball.

Cabrillo swung around and laid down a wall of cover fire as Max and Linc mounted the gangway. Juan stepped onto the sloping ramp and pressed a button under the railing. The five feet of the gangway’s leading edge snapped sharply upward. With its solid sides, and now with the tip elevated ninety degrees, the three men were shielded by the withering return fire from Abala’s men. Bullets whizzed over their heads, smacking into the side of the freighter and ricocheting off the metal skin of the gangway as the trio huddled safely in their armored cocoon.

“Like we wouldn’t see this coming,” Max said casually over the riotous din.

An operator inside the ship worked the controls of the gangplank and it lifted off the dock, allowing the men to dash into the ship’s superstructure. All pretenses aside, Juan took immediate control. He slapped the button on a wall-mounted intercom. “Sit rep, Mr. Murphy.”

Deep inside the freighter, Mark Murphy, chief weapons operator, was watching a monitor showing video from a camera mounted on one of the ship’s five cranes.
